Not when to get that you just burned your only Standard against a bunch of hostile ninja who will get 2 Standards and 4 Supplementals each towards the sole task of killing / beating you before you whatsoever get to act again. Even if you burned ALL those tags on a single dodge, thats literally the same value as one single Level 32 Substitution. And the alternative is getting 5x the Action Economy you had by doing SC opening, and having them actively contribute to the fight.
Also, uh, Akane had more CP than that I'm pretty sure. Its either that or the SC CP numbers you quote are wrong (which they aren't, checked).
She had 320, meaning that making 4 clones would leave her with: 320 - (150+(4 * 25)) = 70 CP which would then distribute across all 5 instances of her, leaving each instance with 14 CP. Which is not enough to do a Substitution without falling unconscious. If a clone falls unconscious it will pop. If Prime falls unconscious, all the clones will pop.
As per your statement above, she is facing "a bunch" of hostile ninja. Unclear on what that means, but I think the following definitions seem reasonable as minimal numbers.
"a few" = 3
"several" = 4
"a bunch" = 5
So, you've now got five 1v1 fights of enemy ninja vs Akane-instance, except each Akane-instance is essentially out of chakra. She can boost at most 2 points, can't Substitute, and can't cast
any jutsu [EDIT: most jutsu, and almost no powerful combat jutsu]. That's you're
best case, where we're assuming that "a bunch of enemy ninja" means 5 and no more, so it's 1v1 instead of multiple-v-1.
Good luck with that. You've been riding this "SC is the best and only combat tactic!" hobby horse for a long time, and I agree that there are many fights where it's a good, or even the best, opener...but I think it's worth considering that it may not be optimal in
every fight.
Last I checked they could cast jutsu of their own too.
Sure, the clones can cast jutsu. Jutsu that cost no more than 13 CP.
you'd either need direct access to the Great Seal (at minimum!) or direct access to a cooperative Primordial Sealmaster.
Note that we gave Hazō the prereq not for
seeing the Great Seal per se, but for having the Great Seal stored in his Iron Nerve memory.
